Yup, Prolimatech or Zalman, The prolimatech is bigger and seems to have a tad more clearance for future compatibility and has removeable mounting brackets that "supposedly" new ones will be released as and when needed and quickly after launch of new cards aswell.
Problem is, if the new brackets don't come out quickly. Then again as is worth noting, Nvidia mounting seems to change one generation to the next, ATi mounting has been fairly similar for several generations using one of two sizes so its likely the Zalman and Prolimatech will work with the next gen AMD cards as is.
Being that Nvidia don't look set to be competitive or affordable for the forseeable future, future compatibility might not be an issue.
They are both massively better than stock cooling, offering much quieter operation at hugely lower temps.
For me the Prolimatech is expensive at £46 for one card, but if it works on a 68xx, and a 78xx aswell then its £15 for ridiculously better cooling per card, at which point its almost a no brainer.
